The substitution key is: To encipher a message, find the letter you wish to encipher in the top row, then replace it with theletter in the bottom row. The Atbash Cipher is a really simple substitution cipher that is sometimes called mirror code. The Atbash cipher is essentially a substitution cipher with a fixed key, if you know the cipher is Atbash,then no additional information is needed to decrypt the message. With a substitution cipher, each character in an alphabet maps to a cryptabet with different characters in the same position. Analytics cookies. An Atbash cipher is a simple substitution cipher wherein a key is used to determine what letters to swap, for example:. A single Transform() method is all you need. The simplicity of the code should not have one assume a lack of depth for meaning, though. The first use of encryption was in ancient Egypt which archeologists discovered when they found an encrypted message in a tomb (after further research they discovered that this seemingly incoherent string of words corresponds to a hidden message in regular hieroglyphics). endstream endobj 15 0 obj <> endobj 16 0 obj <> endobj 17 0 obj <>stream The following is a list of cryptograms fromGravity Falls.
